Hello Douglas,
You are plain wrong!
The experiment you mentionned was done by Bruce Edgar but the comparison was not done between a truncated exponential and a conical horn as you erroneously wrote but between a truncated exponential and a tractrix horn. The voice coming through the Tractrix horn (the profile of which is quasi similar to a Le Cléac'h horn along 90% of the length) was much more natural and uncolored than with the truncated expo.
You'll find the original story in Positive Feedback's interview of Bruce Edgar:
http://www.positive-feedback.com/Issue4/edgarinterview.htm
quote from Positive feedback:
"Dave:Bruce, you have quite effectively demonstrated the difference between Tractrix horn sound quality and exponential horn sound quality, which I've enjoyed seeing you do at CES and the Stereophile Show. You had a couple of horns made out of stiff paper, you just picked them up and spoke through them. I wonder if you can easily characterize the differences between the exponential and the Tractrix?"...
Best regards from Paris,
Jean-Michel Le Cléac'h
